New measurement device and technique for assessing implant and prosthetic motility

Implant and prosthetic motility are key aspects of good cosmesis in an anophthalmic socket. Various techniques have been attempted to improve implant and prosthesis motility. However, the attempts at comparing these techniques are incomplete without a simple, objective, reproducible method of motility measurement. We describe a novel, simple, inexpensive, custom-made slit-lamp measurement device and a new technique to measure implant and prosthetic motility objectively for documentation. To the best of our knowledge, no such device or method has been documented or described in the literature.
